Answer:
kinetic energy is only dependent on temperature
K = 3/2 RT
so the ans is B
if it is correct
mark it as brainlist
Tulsirani100:
But K.E depends on the mass too
K.E =p^2/2m
thats in mechanics , but we are dealing with the kinectic energy of gases
Okay! thanks
see Vrms = √ 3RT /√M. BY applying ke =1/2 mv². u get 3/2RT
Thanks a bundle
mark it as brainlist , so i move to the next rank
I have already marked
thank you

average KE =√8RT/piM where M is atomic mass of given atom. So average KE is inversely proportional to atomic mass. So Hydrogen has more AvKE than Oxygen.
But correct option is b
oh then some other concept is involved may be...but if thermodynamics this is 100% correct
check out formula for V avg !! and K.E. u ll get the answer
yaya
silly mistake!
